Umbhoshongo opakishiwe we-NaOH wokumuncwa i-SO2 uyisisetshenziswa esivamile sokumunca igesi, esivame ukusetshenziswa enqubweni ye-flue gas desulfurization.Umgomo wayo oyinhloko ukufafaza isixazululo se-NaOH ku-wire mesh epakishwe uthayela, ukumunca amagesi e-asidi afana ne-SO2 bese usabela nge-NaOH ukwenza usawoti ohambisanayo, ukuze kufezwe inhloso yokuhlanza igesi ephuma ku-flue.
Umbhoshongo opakishiwe uvame ukwakhiwa ungqimba lokupakisha lwezintambo zikathayela, isisabalalisi se-liquid, indawo yokungenisa umoya, indawo yokukhipha umoya, imbobo yokukhipha uketshezi, imbobo yokukhipha nezinye izingxenye.Isendlalelo sokupakisha esinemeshi yensimbi siwukupakisha okuqinile okugcwele umbhoshongo ogcwele phama, futhi umsebenzi wawo ukukhulisa indawo yokuxhumana nokwandisa ukusebenza kahle kokusabela.I-liquid distributor iyithuluzi elifafaza isisombululo se-NaOH ngokulinganayo emaphaketheni kathayela anezikhala zocingo.I-air inlet isetshenziselwa ukwethula igesi ephumayo equkethe amagesi e-asidi afana ne-SO2, kuyilapho indawo yokukhipha igesi isetshenziselwa ukukhipha igesi ye-flue ehlanzekile.I-liquid outlet isetshenziselwa ukukhipha isisombululo se-NaOH esimunce i-SO2, kuyilapho imbobo yokukhipha isetshenziselwa ukukhipha igesi ephehliwe kanye negesi engaphenduliwe.
Embhoshongweni ogcwele phama, isixazululo se-NaOH sizothinta futhi simunce amagesi e-asidi njenge-SO2 kugesi we-flue, futhi sisabele ukukhiqiza usawoti ohambisanayo.Kule nqubo, izici ezifana nokugxila kwesisombululo se-NaOH, inani lokufafaza, nezinga lokushisa kuzothinta ukusebenza kahle kokumuncwa.Ngakho-ke, ekusebenzeni okusebenzayo, kuyadingeka ukulungisa imingcele yokusebenza yombhoshongo ogcwele ngokuya ngezidingo ezithile zenqubo kanye nezingxenye zegesi ye-flue.
Ngaphezu kwalokho, umbhoshongo ogcwele futhi udinga ukwelashwa kokukhishwa ukuze kuqinisekiswe ukuthi igesi ye-flue ehlanziwe kanye noketshezi olukhishwayo luhlangabezana nezindinganiso zemvelo.Ngokuvamile, ikhambi le-NaOH lizoqoqwa echibini loketshezi eliphansi, futhi lingakhishwa kuphela ngemva kokuba lingathathi hlangothi futhi linemvula.
Ngamafuphi, umbhoshongo wokupakisha we-NaOH wokumuncwa i-SO2 uyisisetshenziswa esibalulekile sokuhlanza igesi.Ngokufafaza isixazululo se-NaOH ekupakishweni kwe-wire mesh kathayela, i-SO2 namanye amagesi ane-asidi ayamuncwa futhi asabelane ne-NaOH ukwenza usawoti, ukuze kufezwe injongo yokuhlanza igesi yomkhuhlane..Ekusetshenzisweni okusebenzayo, kuyadingeka ukulungisa amapharamitha wokusebenza wombhoshongo ogcwele ngokuya ngezidingo zenqubo ethile kanye nezingxenye zegesi eliwuketshezi, futhi wenze ukwelashwa kokukhipha ukungcola ukuze kuhlangatshezwane nezidingo zokuvikela imvelo.
